Commissioning
6.1
Connection
After the supply voltage is connected, the green LED in the voltage connector and
the PWR LED on the display panel must light up. If the LED in the connector lights
up red, the polarity of the power supply is reversed.
6.2
Preliminary considerations
A very important aspect of the operation of an extended identification system on
the DeviceNet is the time response of the overall system. The question "How long
after the positioning of a data carrier in front of a read/write station will the read
data be available in the computer or PLC?" cannot be answered universally.
The most important factors that determine the response time are:
■
Nature of the higher-level host system, e.g. PLC or PC
■
Communication between the client and server
■
Network utilization
■
Number and nature of connected read/write stations
■
Type of code/data carrier used
■
Nature of access to the communication objects of the read/write station
■
Nature of the commands to the read/write station
■
Structure of the user program

Device settings
You must set the various parameters prior to commissioning.
The parameters are volatile and non-volatile parameters. Volatile parameters are
reset to their default setting when the system is switched off and on again.
Warning!
Before commissioning, check once again that the connections are correct.
Before commissioning, familiarize yourself with the system of communication
between your DeviceNet control and the read/write station (see chapter 7).
Commissioning requires accurate knowledge of DeviceNet communication.
Warning!
Device not configured or configured incorrectly
Configure the device prior to commissioning. A device that has not been
configured or configured incorrectly may lead to faults in the plant.
